Description

Technical Field

[0001] This utility model relates to the field of vapor-type electronic cigarette technology, and in particular to a cartridge for vapor-type electronic cigarettes, as well as an electronic cigarette system used in conjunction with the cartridge. Background Technology

[0002] Existing vapor-type electronic cigarettes (i.e., aerosol atomization systems) are nicotine delivery systems that deliver nicotine by heating the atomized e-cigarette to induce a vaporization reaction and produce an aerosol for the consumer to inhale. These systems typically employ a traditional atomizer coil and e-liquid tank structure, using the coil to heat the e-cigarette to generate an aerosol for the consumer to inhale. Because the e-cigarette's oily atomized substance is directly connected to the inhalation channel, these systems are not strictly sealed. The atomized substance can seep into the inhalation channel through the wicking material within the system, resulting in persistent leakage, a significant problem that severely hinders industry development and affects the quality of the inhaled product.

[0003] To address the leakage problem of liquid e-cigarette vaporizers, Chinese utility model patent application CN2024112435296 discloses a novel e-cigarette cartridge, the structure of which includes a tubular outer shell (1), a lower plug and an upper plug installed inside the tubular outer shell, a magnetic heating element (4) fixed between the lower plug and the upper plug (3), and an e-cigarette vaporizer carrier (5). The magnetic heating element (4) is a hollowed-out tubular shape, and the middle of the magnetic heating element (4) has a vapor flow channel (41) arranged along the length direction. The electronic cigarette atomizer carrier (5) is a column with a hollow flow channel (51) arranged along the length direction. Its outer diameter is not greater than the inner diameter of the tubular shell (1). The electronic cigarette atomizer carrier (5) is sleeved on the outside of the magnetic heating element (4). The inner surface of the electronic cigarette atomizer carrier (5) is adjacent to the outside of the magnetic heating element (4). Electronic cigarette atomizers are adsorbed inside the electronic cigarette atomizer carrier (5). The lower plug hole (21), the smoke flow channel (41), the upper plug hole (31), and the mouthpiece section (200) are connected.

[0004] The inventors discovered in practical applications that the structure of this novel e-cigarette cartridge could be further optimized to simplify the structure, significantly reduce production costs and improve production efficiency, and therefore proposed this utility model. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and, through structural improvements, provide a new type of e-cigarette cartridge with a simpler structure for use with vapor-type electronic cigarettes.

[0006] To achieve the above objectives, this utility model provides a simple e-cigarette cartridge, which includes a tubular outer shell 1, a central plug 3 installed in the middle section inside the tubular outer shell 1, and an electronic atomizing carrier 5 located in the lower section inside the tubular outer shell 1. The tubular outer shell 1 is made of non-metallic material, and the central plug 3 has a central plug through hole 31 arranged along the length direction; the area inside the tubular outer shell 1 and above the central plug 3 is the mouthpiece section 200.

[0007] Among them, the electronic smoke atomizing carrier 5 is a hollow column made of porous adsorbent material, or a hollow column formed by rolling and stacking layered adsorbent material, and the middle part of the hollow column is a heating rod insertion hole 51 arranged along the length direction.

[0008] The tubular outer shell 1, the middle plug 3, and the electronic atomizing carrier 5 are assembled together to connect the heating rod insertion hole 51, the middle plug through hole 31, and the mouthpiece section 200.

[0009] In this utility model, in particular, the lower inner diameter of the middle through hole 31 is larger than its upper inner diameter, and the lower inner diameter of the middle through hole 31 is larger than the inner diameter of the heating rod insertion hole 51.

[0010] In this invention, for ease of description and not limitation, the direction toward the electronic cigarette device 300 is referred to as "down," and the direction toward the mouthpiece section 200 is referred to as "up." This up-down direction is also called the length direction.

[0011] In this invention, the tubular outer shell 1 has the shape of a hollow tube, and the other components installed therein therefore have the shape of a column or hollow column to facilitate their assembly. For ease of manufacture, their cross-sections can be circular, but other cross-sections of polygonal hollow tubes or polygonal hollow columns can also achieve similar functionality.

[0012] In this invention, describing the through holes (such as the heating rod insertion hole 51, the central plug through hole 31, and the nozzle section 200) as being arranged along the length direction means that these through holes connect the upper and lower ends of the component to allow aerosol to pass through each component, and does not limit the shape of the through holes. The through holes can be straight holes or curved flow channels. When certain components are made of breathable materials, such as filter rods made of conventional filter rod materials like foamed silicone or cellulose acetate, through holes are unnecessary because flue gas can pass through these materials.

[0013] Optionally, a filter rod 6 may be provided in the suction section 200. The filter rod 6 is typically used to reduce the aerosol temperature, adsorb some substances in the aerosol, or adsorb a small amount of liquid that condenses in the area due to local temperature reduction. The filter rod 6 may be made of porous material, foam material, or cellulose acetate tow with a certain air resistance, or it may have a flue gas channel arranged along its length in the middle of the filter rod.

[0014] Furthermore, to facilitate assembly or positioning, conventional mechanisms such as limiting protrusions for restricting filter rod displacement can be provided on the inner wall of the nozzle section 200.

[0015] In this invention, the e-cigarette atomizer carrier 5 is used to adsorb and load e-cigarette atomizers (commonly known as e-cigarette liquids). When it comes into direct contact with a heating element (such as the heating rod 304 installed in the e-cigarette system), the e-cigarette atomizers on the carrier are heated to generate aerosols. Therefore, to achieve this function, the e-cigarette atomizer carrier 5 can be a hollow column made of porous adsorbent material, or a hollow column composed of rolled and stacked layered adsorbent material, or they can be wrapped around the outside of the magnetic heating element 4. As long as it can achieve the adsorption of liquid substances and has a certain degree of air permeability, the technical solution of this invention can be realized.

[0016] In this invention, the layered absorbent material comprises one or more of the following materials: high-temperature resistant natural fiber cotton and / or non-woven fabric and / or one or more layers of man-made fiber non-woven fabric and / or oil-absorbing cotton. Each material can be a single layer or multiple layers. High-temperature resistant natural fiber cotton, such as high-temperature resistant flax cotton, is a commercially available material. These layered absorbent materials can be used individually or in combination, and all possess certain adsorption properties and breathability.

[0017] In this invention, the tubular outer shell 1 is made of non-metallic material. In this invention, non-metallic material refers to all materials other than metallic materials. These materials do not possess the properties of metallic materials and do not generate induced electromotive force, eddy currents, or heat in an alternating magnetic field, nor do they shield the magnetic field. Non-metallic materials can be organic, inorganic, or various materials obtained by physical or chemical treatment of organic and inorganic materials. Rubber, ceramics, wood, paper, and various plastics can all be used to implement the technical solution of this invention. Preferably, the tubular outer shell 1 is made of food-grade PC material. To prevent excessive aging of the outer shell material, the central plug 3 is preferably made of silicone, which provides a certain degree of heat resistance.

[0018] Considering that electronic cigarette systems are typically handheld in size, the outer diameter of the tubular housing 1, as part of a portable handheld device, is typically 4-30 mm and the length is 2-8 cm.

[0019] This utility model also provides an electronic cigarette system for use with the aforementioned tobacco cartridge. The electronic cigarette system has a heating chamber 301 for inserting the tobacco cartridge. A heating rod 304 protruding upward is provided at the bottom of the heating chamber 301. The outer diameter of the heating rod 304 matches the inner diameter of the heating rod insertion hole 51. An air outlet 302 is also provided at the bottom of the heating chamber 301. An air inlet 303 is provided on the outer shell of the electronic cigarette system. The air outlet 302 and the air inlet 303 are connected through an air flow channel. When the tobacco cartridge is inserted into the heating chamber 301, the position of the air outlet 302 matches the bottom of the electronic cigarette atomizing carrier 5.

[0020] Vapor-type electronic cigarette systems that achieve heating through electromagnetic induction or through a heating rod are existing technologies in this field. Such systems typically include an electronic cigarette casing, a battery housed within the casing, and necessary electronic control components (for products that achieve heating through electromagnetic induction, an electromagnetic induction coil connected to the battery should also be included).

[0021] In use, the cartridge of this invention is placed in the heating chamber 301 of the electronic cigarette. The heating rod 304 heats up under electronic control, so that the electronic atomizing agent on the carrier 5 in contact with it is heated to a specific temperature to generate vapor. Under the negative pressure provided by the user's inhalation action, the vapor flows through the electronic atomizing agent carrier 5 along with the air from the air outlet 302, through the central plug hole, and into the mouthpiece section.

[0022] The e-cigarette cartridge of this invention is characterized by its small size, simple structure, and ease of production and manufacturing. Attached Figure Description

[0039] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.

[0040] Example 1

[0041] like Figure 1-2 The e-cigarette cartridge shown includes a tubular shell 1 made of food-grade PC, a central plug 3 made of silicone, a cellulose acetate filter rod 6 located above the central plug 3, and an electronic atomizing carrier 5 located below the central plug.

[0042] Central Severance Figure 6 As shown, it has a central through hole 31.

[0043] Electronic vapor carrier 5 such as Figure 7 As shown, non-woven fabric is wound into a basically hollow cylindrical shape, with a heating rod insertion hole 51 in the middle, and then installed inside the tubular outer shell 1. Because it is made of non-woven fabric, it possesses both adsorption and breathability properties. Liquid electronic atomizing agents are adsorbed within the electronic atomizing agent carrier 5.

[0044] The electronic cigarette system used with the cartridge has a heating chamber 301 for inserting the cartridge. A heating rod 304 protruding upwards is provided at the bottom of the heating chamber 301. The outer diameter of the heating rod 304 matches the inner diameter of the heating rod insertion hole 51. The heating rod can generate heat under the control of the electronic cigarette system. Furthermore, to ensure that the smoke can be inhaled, the electronic cigarette casing is provided with an air inlet 303, which is connected to an air outlet 302 via an airflow channel. When the cartridge in this embodiment is inserted into the heating chamber 301, the position of the air outlet 302 matches the bottom of the electronic cigarette atomizer carrier 5.

[0045] In use, the novel tobacco cartridge of this invention is placed in the heating chamber of an electromagnetic induction heating electronic cigarette system. When the heating rod is heated in a controlled manner, the electronic atomized material on the electronic cigarette atomizer carrier 5, which is in contact with the heating rod, is heated to a specific temperature, generating vapor. As the consumer inhales, air enters from the air inlet 303, flows from the air outlet 302 to the electronic atomized material carrier 5, then enters the central plug hole, and then flows with the vapor to the mouthpiece section.

[0046] The cigarette cartridge of this invention has a simple structure, which effectively reduces production costs and improves production efficiency.
